Die Figur 1 zeigt in einer Explosionsdarstellung eine elektromechanische Verriegelungseinheit 1 für eine Lenksäule eines Kraftfahrzeugs. Die 1 shows an exploded view of an electromechanical locking unit 1 for a steering column of a motor vehicle. The
Verriegelungseinheit 1 weist ein Gehäuse 2 auf, in dem ein Elektromotor 3 mit einer Motorwelle 4 und einem angetriebenen Schneckenrad 5 montiert ist. Das Schneckenrad 5 kämmt in montiertem Zustand mit einem Zahnrad 6, welches drehfest mit einem Kulissenrad 7 verbunden ist. Das Kulissenrad 7 weist umfangsseitig eine Kulisse 8 auf, in die in montiertem Zustand ein Mitnehmer 9 eines Rastbolzens 10 eingreift. Der Rastbolzen 10 ist mittels einer Schraubenfeder 11 in die in Figur 1 nach unten weisende Richtung Locking unit 1 has a housing 2, in which an electric motor 3 with a motor shaft 4 and a driven worm wheel 5 is mounted. The worm wheel 5 meshes in the assembled state with a gear 6, which is rotatably connected to a sliding gear 7. The sliding gear 7 has on the circumference a gate 8, in the assembled state, a driver 9 of a locking bolt 10 engages. The locking pin 10 is by means of a Coil spring 11 in the direction pointing downwards in Figure 1 direction
vorgespannt. Das Zahnrad 6 und das Kulissenrad 7 sind in dem Gehäuse 2 drehbar gelagert. biased. The gear 6 and the guide wheel 7 are rotatably mounted in the housing 2.
Weiter trägt das Gehäuse 2 einen Montagebereich 12 für eine Leiterplatte 13 und eine Abdeckplatte 14. In dem Montagebereich 12 sind außerdem ein magnetischer Flusssammler 15 sowie eine elektrische Kontaktierung 16 angeordnet. Die elektrische Kontaktierung 16 ist als Steckverbindung ausgeführt und dient zum Anschluss einer elektrischen Leitung 17 mittels eines mehrpoligen Steckers 18, wobei die elektrische Leitung 17 nicht Teil der Baugruppe der elektromechanischen Verriegelungseinheit 1 ist. Next, the housing 2 carries a mounting portion 12 for a printed circuit board 13 and a cover plate 14. In the mounting portion 12, a magnetic flux collector 15 and an electrical contact 16 are also arranged. The electrical contact 16 is designed as a plug connection and is used to connect an electrical line 17 by means of a multi-pole plug 18, wherein the electrical line 17 is not part of the assembly of the electromechanical locking unit 1.
Der montierte Zustand der elektromagnetischen Verriegelungseinheit 1 an einer Lenkwelle 20 ist in der Figur 2 veranschaulicht, wobei das Gehäuse 2 zur besseren Übersichtlichkeit weggelassen wurde. Gleiche oder funktionsgleiche Bauelemente tragen hier, wie auch in der weiteren Figurenbeschreibung, gleiche Bezugsziffern. Zur besseren Übersichtlichkeit können einige The assembled state of the electromagnetic lock unit 1 on a steering shaft 20 is illustrated in FIG. 2, with the housing 2 omitted for clarity. Same or functionally identical components bear here, as well as in the further description of the figures, the same reference numerals. For clarity, some
Bezugsziffern nicht wiederholt aufgeführt sein. Reference numerals will not be listed repeatedly.
Die Figur 2 zeigt also die Verriegelungseinheit 1 mit dem Elektromotor 3, der über die Motorwelle 4 und das Schneckenrad 5 das Zahnrad 6 antreibt. Das Zahnrad 6 wiederum treibt das Kulissenrad 7 an, in dessen Kulisse 8 der hier nicht sichtbare Zapfen 9 des Rastbolzens 10 eingreift. Das Kulissenrad 7 ist in unmittelbarer Nähe der Leiterplatte 13 angeordnet. Die Leiterplatte 13 ist wiederum mit dem Flusssammler 15 zusammen unmittelbar neben einem Drehwinkelgeber 21 montiert, so dass der Drehwinkelgeber 21, dessen 2 thus shows the locking unit 1 with the electric motor 3, which drives the gear 6 via the motor shaft 4 and the worm wheel 5. The gear 6 in turn drives the guide wheel 7, engages in the slot 8 of the not visible here pin 9 of the locking bolt 10. The guide wheel 7 is arranged in the immediate vicinity of the printed circuit board 13. The circuit board 13 is in turn mounted together with the flux collector 15 adjacent to a rotary encoder 21, so that the rotary encoder 21, whose
Magnetfeld über den Flusssammler 15 geleitet und konzentriert wird, ein magnetisches Feld an erste Sensoren auf der Leiterplatte 13 abgibt. Die ersten Sensoren sind dazu geeignet und eingerichtet, die Winkelposition des Magnetic field is passed through the flux collector 15 and concentrated, a magnetic field to first sensors on the circuit board 13 emits. The first sensors are suitable and adapted to the angular position of the
Drehwinkelgebers 21 und der damit verbundenen Lenkwelle 20 zu erfassen und auszuwerten. Je nach Ausführung kann dies als Lenkwinkelsensor oder als Lenkdrehmomentsensor vorgesehen sein. In der hier dargestellten Rotary encoder 21 and the associated steering shaft 20 to detect and evaluate. Depending on the design, this may be provided as a steering angle sensor or as a steering torque sensor. In the illustrated here
Ausführungsform handelt es sich um einen Drehmomentsensor. Embodiment is a torque sensor.
Die Leiterplatte 13 trägt weiter einen zweiten Sensor (hier nicht sichtbar), der die Position des Kulissenrades 7 abfragt. Es wird nur die Endstellung des Kulissenrades 7, also die Endposition in beiden Drehrichtungen, abgefragt. Durch die mechanische Zwangskopplung des Kulissenrades 7 mit dem The printed circuit board 13 further carries a second sensor (not visible here), the queries the position of the guide wheel 7. It is only the end position of the guide wheel 7, so the end position in both directions, queried. Due to the mechanical forced coupling of the guide wheel 7 with the
Rastbolzen 10 ist damit auch die Position des Rastbolzens 10 in den Endlagen erfassbar. Detent pin 10 is thus the position of the locking bolt 10 detected in the end positions.
Die Lenkwelle 20 trägt weiter einen Raststern 22, in dem der Rastbolzen 10 in bekannter Weise eingreifen kann, um die Lenkwelle zu arretieren und damit einen Lenkvorgang zu unterbinden, um eine unbefugte Benutzung des The steering shaft 20 further carries a detent star 22 in which the locking pin 10 can engage in a known manner to lock the steering shaft and thus to prevent a steering operation to prevent unauthorized use of
Kraftfahrzeugs auch im Wege des Schiebens oder Abschleppens zu Motor vehicle also by way of pushing or towing
verhindern. Dazu kann der Elektromotor 3 bestromt werden. In einer ersten Drehrichtung des Elektromotors 3 kann der Rastbolzen 10 in dem Raststern 22 hineingefahren werden, so dass die Lenkwelle 20 blockiert wird. Bei prevent. For this purpose, the electric motor 3 can be energized. In a first direction of rotation of the electric motor 3, the latching bolt 10 can be moved into the latching star 22, so that the steering shaft 20 is blocked. at
Bestromung in entgegengesetzter Richtung fährt der Elektromotor 3 den Rastbolzen 10 aus dem Raststern 22 heraus und gibt die Lenkwelle 20 damit frei. Die Erkennung der Endlagen mit dem zweiten Sensor ermöglicht einerseits die Auswertung des Signals für Steuerungszwecke und andererseits die Abschaltung des Elektromotors 3 bei Erreichen der jeweils angestrebten Endlage, so dass der Elektromotor 3 nicht unnötig lange bestromt werden muss, andererseits aber die Endlage zuverlässig erreicht wird und dies auch geprüft werden kann. Energization in the opposite direction, the electric motor 3 drives the locking pin 10 out of the star catch 22 and releases the steering shaft 20 with it. The detection of the end positions with the second sensor allows on the one hand the evaluation of the signal for control purposes and on the other hand, the shutdown of the electric motor 3 upon reaching the respective desired end position, so that the electric motor 3 does not need to be energized unnecessarily long, but on the other hand, the end position is reliably achieved and this can also be checked.
Die Figur 3 zeigt die Anordnung aus Figur 2 in einer anderen Ansicht. Es ist ersichtlich, dass der Rastbolzen 10, der hier in seiner Eingriffsstellung in dem Raststern 22 dargestellt ist, dass nicht dargestellte Gehäuse 2 auf den FIG. 3 shows the arrangement from FIG. 2 in another view. It can be seen that the locking pin 10, which is shown here in its engaged position in the latching star 22 that not shown housing 2 on the
Raststern zu durchgreift. Angesichts der erheblichen Kräfte, die auf eine Lenkwellenverriegelung im Missbrauchsfall wirken, ergibt sich hieraus, dass die Lagerung des Rastbolzens 10 nicht vollständig in der Verriegelungseinheit 1 erfolgen kann. Dies wird nachfolgend noch näher erläutert. Raststern to reach through. In view of the considerable forces acting on a steering shaft lock in case of abuse, it follows that the storage of the locking bolt 10 can not be done completely in the locking unit 1. This will be explained in more detail below.
Die Figur 4 zeigt die Lenksäule aus den Figuren 2 und 3 in einer FIG. 4 shows the steering column from FIGS. 2 and 3 in one
perspektivischen Darstellung mit weiteren Komponenten. Gegenüber der Darstellung der Figuren 2 und 3 ist hier das Gehäuse 2 der perspective view with other components. Compared with the illustration of Figures 2 and 3, here the housing 2 of
Verriegelungseinheit 1 dargestellt. Das Gehäuse 2 trägt und lagert den Locking unit 1 shown. The housing 2 carries and supports the
Elektromotor 3 sowie die übrigen in Figur 1 dargestellten Bauteile. Das Gehäuse 2 selbst ist auf einem Gehäuseteil 23 angeordnet, welches Teil der Lenksäule ist und eine Lagerung der Lenkwelle 20 aufweisen kann, derart, dass die Lenkwelle 20 in dem Gehäuseteil 23 drehbar gelagert ist. Electric motor 3 and the other components shown in Figure 1. The Housing 2 itself is arranged on a housing part 23, which is part of the steering column and may have a bearing of the steering shaft 20, such that the steering shaft 20 is rotatably mounted in the housing part 23.
Insbesondere umgibt das Gehäuseteil 23 umfangseitig auch den Raststern 22 und lagert den in dieser Darstellung nicht sichtbaren Rastbolzen 10 derart, dass der Rastbolzen 10 in einer im Wesentlichen radialen Richtung auf den Raststern 22 zu verschiebbar ist, dass auftretende Querkräfte, die von dem Raststern bei einer manuellen Drehbewegung der Lenkwelle 20 ausgeübt werden, aber von dem Gehäuseteil 23 aufgenommen werden können, ohne dass eines der Bauteile beschädigt wird. Auch hier wird deutlich, dass das Gehäuse 2 mit seiner dünnwandigen und entsprechend leichten Ausgestaltung für die Aufnahme solcher Kräfte im Missbrauchsfall nicht ausreichend dimensioniert ist. In particular, the housing part 23 circumferentially surrounds the detent star 22 and stores the not visible in this illustration locking pin 10 such that the locking pin 10 in a substantially radial direction on the detent star 22 is displaced that occurring transverse forces from the rest star in a manual rotational movement of the steering shaft 20 are exercised, but can be absorbed by the housing part 23 without any of the components is damaged. Again, it is clear that the housing 2 is not sufficiently dimensioned with its thin-walled and correspondingly lightweight design for receiving such forces in case of abuse.
Die Figur 5 zeigt eine weitere Zusammenbaustufe der Lenksäule aus Figur 4. Die Baugruppe aus Figur 4 ist hier um weitere Bauteile ergänzt. So ist insbesondere unmittelbar an das Gehäuseteil 23 ein zweites Gehäuseteil 24 montiert, welches eine an sich bekannte Versteileinrichtung 25 für die FIG. 5 shows a further assembly stage of the steering column from FIG. 4. The assembly from FIG. 4 is supplemented here by further components. Thus, in particular directly to the housing part 23, a second housing part 24 is mounted, which is a known adjusting device 25 for the
Höhenverstellung der Lenksäule und eine ebenso bekannte Versteileinrichtung 26 für die axiale Verstellung der Lenksäule umfasst. Das zweite Gehäuseteil 24 trägt auch ein äußeres Mantelrohr 27, in dem ein lenkradseitiger Teil 28 der gesamten Lenkwelle drehbar gelagert ist. Der lenkradseitige Teil 28 weist eine Verzahnung 29 zur Montage eines Lenkrades auf. Die Lenkwelle 20 in Figur 4 weist ein unrundes, insbesondere etwa kleeblattförmiges äußeres Profil auf. Der Lenkwellenteil 28 weist ein entsprechend kompatibles inneres Profil auf, so dass die beiden Lenkwellenteile 20 und 28 ineinander greifen können und eine drehfeste, aber teleskopierbare Anordnung bilden. An dem Height adjustment of the steering column and an equally known adjusting device 26 for the axial adjustment of the steering column comprises. The second housing part 24 also carries an outer jacket tube 27, in which a steering wheel side part 28 of the entire steering shaft is rotatably mounted. The steering wheel-side part 28 has a toothing 29 for mounting a steering wheel. The steering shaft 20 in Figure 4 has a non-round, in particular approximately cloverleaf-shaped outer profile. The steering shaft part 28 has a correspondingly compatible inner profile, so that the two steering shaft parts 20 and 28 can mesh with each other and form a rotationally fixed, but telescopic arrangement. To the
gegenüberliegenden Ende der Lenksäule ist ein weiteres Gehäuseteil 30 angeordnet, welches einerseits Lagerstellen 31 für die schwenkbare Lagerung der Lenksäule an einer Konsole 37 in einem Kraftfahrzeug trägt und welches andererseits eine Lagerung für eine Antriebswelle eines Servoantriebs 32 trägt. Die Antriebswelle, deren Lagerung und das Getriebe zur Kopplung des Servoantriebs an die Lenkwelle 20, sind aus dem Stand der Technik bekannt und hier nicht näher dargestellt. Die Gehäusteile 23, 24 und 30 bilden zusammen mit anderen kleineren another housing part 30 is arranged opposite end of the steering column, which on the one hand carries bearing points 31 for the pivotable mounting of the steering column on a bracket 37 in a motor vehicle and on the other hand carries a bearing for a drive shaft of a servo drive 32. The drive shaft, the bearing and the gearbox for coupling the servo drive to the steering shaft 20 are known from the prior art and not shown here. The housing parts 23, 24 and 30 together with other smaller
Bauteilen die sogenannte Kastenschwinge, die zum einen als wesentliches tragendes Bauteil der Lenksäule die Lagerung der Lenkwelle 20 aufnimmt und die zum anderen die oben genannten Verstellmöglichkeiten in Vertikalrichtung (vom Fahrer aus gesehen) und in Axialrichtung der Lenksäule ermöglicht. Die Bezeichnung„Kastenschwinge" ergibt sich aus dem kastenförmigen Aufbau und der endseitigen Lagerung in den Lagerstellen 31, die diese Baugruppe wie eine Schwinge an einer Konsole 37 schwenkbar lagert. Components, the so-called box rocker, on the one hand as an essential structural component of the steering column, the bearing of the steering shaft 20 receives and on the other allows the above-mentioned adjustment in the vertical direction (from the driver) and in the axial direction of the steering column. The term "box rocker" results from the box-shaped structure and the end-side storage in the bearings 31, which supports this assembly such as a rocker on a bracket 37 pivotally.
Der Servoantrieb 32 weist üblicherweise einen bürstenlosen Elektromotor auf, der von einer Steuerung 33 angesteuert wird. Bei diesem Ausführungsbeispiel ist die Steuerung 33 über die Leitung 17, die bereits oben mit Bezug auf Figur 1 beschrieben wurde, mit der Verriegelungseinheit 1 verbunden. Über die Leitung 17 werden die ersten Sensoren des Drehmomentsensors und die zweiten Sensoren für die Abfrage der Endlagen der Lenkungsverriegelung abgefragt. Außerdem wird über das Kabel 17 die Versorgungsspannung für den Elektromotor 3 der Verriegelungseinheit 1 geleitet. Aus diesem Ausbau ergeben sich mehrere Vorteile, die konstruktiv genutzt werden können. Zum einen ist nur eine elektrische Verbindung zwischen der Verriegelungseinheit 1 und der Steuerung 33 erforderlich, was Kosten und Montagezeit minimiert. Zum anderen liegen die Daten des Drehmomentsensors und der Verriegelung (Endlagensensor) über dieselbe Kabel- oder Steckverbindung in der Steuerung 33 vor. Der Aufbau der Verriegelungseineheit 1 kann mit leichten Materialien erfolgen, da die wesentlichen Kräfte, die im Missbrauchsfall auftreten, von dem Rastbolzen 10 nicht in das Gehäuse 2 der Verriegelungseinheit 1 eingeleitet werden, sondern in das Gehäuseteil 23 der Kastenschwinge. The servo drive 32 usually has a brushless electric motor, which is controlled by a controller 33. In this embodiment, the controller 33 is connected to the locking unit 1 via the line 17 already described above with reference to FIG. Via the line 17, the first sensors of the torque sensor and the second sensors are queried for the query of the end positions of the steering lock. In addition, the supply voltage for the electric motor 3 of the locking unit 1 is passed through the cable 17. From this expansion, there are several advantages that can be used constructively. Firstly, only an electrical connection between the locking unit 1 and the controller 33 is required, which minimizes costs and installation time. On the other hand, the data of the torque sensor and the locking (end position sensor) via the same cable or connector in the controller 33 before. The structure of the locking unit 1 can be made with lightweight materials, since the essential forces that occur in abuse, are not initiated by the locking pin 10 in the housing 2 of the locking unit 1, but in the housing part 23 of the box rocker.
Dementsprechend kann die Verriegelungseinheit 1 relativ leicht und klein aufgebaut werden. Der Elektromotor 3 kann deshalb ebenfalls klein gehalten werden und mit geringem Strom angetrieben werden. Auch dieses Merkmal ist vorteilhaft, da die elektrische Verbindung 17 nur entsprechend geringe Ströme übertragen muss und deshalb nur geringe Leitungsquerschnitte benötigt werden. Accordingly, the lock unit 1 can be made relatively light and small. The electric motor 3 can therefore also be kept small and driven with low power. This feature is also advantageous since the electrical connection 17 only has to transmit correspondingly low currents and therefore only small line cross sections are required.
Die Figur 6 zeigt eine weitere Baustufe der erfindungsgemäßen Lenksäule. In dieser Baustufe ist das Gehäuse 2 an seiner Oberseite mit einem Deckel 35 verschlossen. Das Gehäuseteil 24 ist in dieser Darstellung nicht vorhanden. FIG. 6 shows a further construction stage of the steering column according to the invention. In This construction stage, the housing 2 is closed at its top with a lid 35. The housing part 24 is not present in this illustration.
Der vollständige Zusammenbau der Lenksäule ist in Figur 7 dargestellt. Die Lenksäule ist gegenüber der Darstellung aus Figur 6 weiter komplettiert mit einem Montagesockel 36 für die Lenkstockschalter des Fahrzeugs, mit einer Konsole 37 zur Befestigung der Lenksäule am Chassis eines Fahrzeugs, sowie mit einem Spannhebel 38, der sowohl die vertikale Verstellung 25 als auch die axiale Verstellung 26 über einen Spannbolzen 39 wahlweise löst oder verriegelt. Bei der Lenksäule, wie sie in der Figur 7 dargestellt ist, sind bereits alle Komponenten für die elektrische Servounterstützung (Motor 32 und Steuerung 33) ebenso wie die elektromechanische Verriegelungseinheit 1 montiert. Der für die Steuerung des Servoantriebs erforderliche The complete assembly of the steering column is shown in FIG. The steering column is compared with the representation of Figure 6 further completed with a mounting base 36 for the steering column switch of the vehicle, with a bracket 37 for attachment of the steering column on the chassis of a vehicle, as well as with a clamping lever 38, both the vertical adjustment 25 and the axial Adjustment 26 via a clamping bolt 39 selectively triggers or locks. In the steering column, as shown in Figure 7, all components for the electric power assistance (motor 32 and control 33) as well as the electromechanical locking unit 1 are already mounted. The required for the control of the servo drive
Drehmomentsensor ist in der oben beschriebenen Weise realisiert. Die Torque sensor is realized in the manner described above. The
Kontaktierung des Drehmomentsensors und der elektromechanischen Contacting the torque sensor and the electromechanical
Verriegelungseinheit 1 erfolgt über ein einziges Kabel 17, das bereits in der endgültigen Weise an der Lenksäule angebracht ist und die Steuerung 32 mit der Verrigelungseinheit 1 sowie mit dem zugeordneten Drehmomentsensor verbindet. Diese Verbindung kann deshalb bereits bei der Montage der Lenksäule vor dem Einbau an das Kraftfahrzeug erstellt und getestet werden. Für die endgültige Kontaktierung nach der Montage der Lenksäule im Locking unit 1 via a single cable 17, which is already mounted in the final manner on the steering column and connects the controller 32 with the Verrigelungseinheit 1 and with the associated torque sensor. This connection can therefore already be created and tested during installation of the steering column before installation to the motor vehicle. For final contact after installation of the steering column in the
Kraftfahrzeug ist nur noch eine einzige Steckverbindung 40 an der Steuerung 33 vorgesehen. Motor vehicle only a single connector 40 is provided on the controller 33.
Die so beschriebene Lenksäule ist deshalb in ihrem Aufbau kompakt, leicht und mit geringem Aufwand in einem Kraftfahrzeug zu montieren. Die Funktion ist besonders zuverlässig, da der gesamte Zusammenbau insbesondere des Sensors für den Lenkungsparameter (hier: Drehmoment) und die The steering column thus described is therefore compact in construction, easy to install and with little effort in a motor vehicle. The function is particularly reliable, since the entire assembly in particular of the sensor for the steering parameters (here: torque) and the
elektromechanische Verriegelung bereits beim Hersteller der Lenksäule montiert und getestet werden kann. Electromechanical lock can already be mounted and tested by the manufacturer of the steering column.
Die genannten Vorteile ergeben sich im Wesentlichen auch dann, wenn der Servoantrieb anders als in dem dargestellten Ausführungsbeispiel nicht an der Lenksäule, sondern an dem Lenkgetriebe im Bereich der Vorderachse angeordnet ist. Auch in diesem Fall ergeben sich Vorteile durch die gemeinsame Montage der Sensoren auf einer gemeinsamen Leiterplatte und die einheitliche Kontaktierung der Sensoren un der elektromechanischen Verriegelung über eine einzige elektrische Verbindung. The stated advantages are essentially also obtained when the servo drive, unlike in the illustrated exemplary embodiment, is not arranged on the steering column but on the steering gear in the region of the front axle. Also in this case, there are advantages through the common mounting of the sensors on a common circuit board and the uniform contacting of the sensors and the electromechanical lock via a single electrical connection.
